Be.it-known ,,that I, RICHARD, GRAY, of Bloomin'gton, in the county of McLean and State of Illinois, have invented certain new and useful Improvements in Metal Piles; and? I do hereby declarethe 'folldwing tobe a it'ull clear, and exact description of the invention, ,suchas will enable others skilled in the art 'to' which it ap'pertains remake and us'eQthe Myinvention relates'to an improvementin metal piles, the object of the. said invention being .to provide a pile adapted te'be' erected-- without the employment of expertf labor: or
